The brickwork surface was treated with high-pressure water to removal all contaminants prior to repairs and repointing using MasterSeal 590 rapid-setting mortar. The dry brick substrate was primed with one coat of MasterTop P 660 rapid-setting polyurethane primer and a topcoat comprised of two coats of MasterSeal M 336 flexible epoxy polyurethane coating. The use of MasterSeal 590 allowed the repairs to be primed after one day. MasterTop P 660 rapid setting polyurethane primer enabled the MasterSeal M 336 topcoat to be applied without delay, reducing the overall application time by several days from preparation to commissioning.
